Answer: Electric energy
Explanation: Electrical energy is stored between plates in electric field
Answer:
Jeweler B = more accurate
Jeweler A = more precise
Error:
0.008, 0
% error :
0.934% ; 0
Explanation:
Given that:
True mass of nugget = 0.856
Jeweler A: 0.863 g, 0.869 g, 0.859 g
Jeweler B: 0.875 g, 0.834 g, 0.858 g
Official measurement (A) = 0.863 + 0.869 + 0.859 = 2.591 / 3 = 0.864
Official measurement (B) = 0.875 + 0.834 + 0.858 = 2.567 / 3 = 0.8556
Accuracy = closeness of a measurement to the true value
Accuracy = true value - official measurement
Jeweler A's accuracy :
0.856 - 0.864 = - 0.008
Jeweler B's accuracy :
0.856 - 0.856 = 0.00
Therefore, Jeweler B's official measurement is more accurate as it is more close to the true value of the gold nugget.
However, Jeweler A's official measurement is more precise as each Jeweler A's measurement are closer to one another than Jeweler B's measurement which are more spread out.
Error:
Jeweler A's error :
0.864 - 0.856 = 0.008
% error =( error / true value) × 100
% error = (0.008/0.856) × 100% = 0.934%
Jeweler B's error :
0.856 - 0.856 = 0 ( since the official measurement as been rounded to match the decimal representation of the true value)
% error = 0%
Each type of electromagnetic radiation and placed in order of increasing photon energy and increasing frequency
- FM Radio waves < Visible light < X - rays
- Order of increasing frequency.
- FM Radio waves < Visible light < X - rays
This is further explained below.
<h3>What is
electromagnetic radiation?</h3>
Parameters
Frequency =107 100 000 hertz
Wavelength, λ = c / ν => 2.8 m => 2.12 * 10-10 m
Energy = 3.97 * 10 -19 J/ photon.
Generally, the equation for Wavelength is mathematically given as
λ = h c / E
Therefore
λ =6.626 * 10-34 * 3 * 108 / (3.97* 10 -19 J)
λ =5 * 10-7 m
In conclusion, This is considered to be part of the viewable area (green Increasing photon energy from lowest to highest.
- FM Radio waves < Visible light < X - rays
- Order of increasing frequency.
- FM Radio waves < Visible light < X - rays

Answer:
C
Explanation:
Nebulization is the process by which a mist of a substance is introduced into a flame so that the free atoms are formed. The free atoms are now introduced into the light path for Atomic Absorption spectrophotometry.
Answer:
work done = 750 J
Explanation:
Given data:
Force on object = 50 N
Distance covered = 15 m
Work done = ?
Solution:
W = F. d
W = work done
F = force
d = distance
Now we will put the values in formula.
W = 50 N × 15 m
W = 750 N. m = 750 J
